Specification of Letters Patent.

Patented June 8, .1915.

Application fue-a May i5, 1914. serial no. $38,227.

To aZ'Z 'whom 'it 'may concern z Be it known 'that I, HENRY F. PAULEY, a

citizen fof'the United States,'residing at Sacramento, in the county of Sacramento and State of California, have invented new and useful Improvements in Bolts, of which the following is a specification.

The present invention relates to improvements in securing or connecting means for a bolt or screw and is primarily adapted for employment in places where a nut cannotconveniently be arranged to connect with lthe bolt, the object 'of the invention being to provide a device of this character which shall be self-propelling and obviates 'the liability of the loosening or withdrawal of the same, and which shall engage with -and retain4 a bolt.

With the above vrecited object in View, and others which will appear as the nature of the improvement is more fully understood, the improvement resides in the construction, combination and arrangement of parts set forth in the following specifica.- tion and falling within the scope of the appended claims.

In the drawing: Figure 1 is a sectional View taken through a socket showing the application of my improvement, Fig. 2 is a perspective view of the socket member, the fingers or prongs thereof-being illustrated in their outward swinging position, Fig. 3 is a view similar to Fig. 1 but illustrating the screw engaging the lfingers of. prongs to swingthe same to engagement with the structure upon which the socket is arranged, Fig. 4 is a longitudinal sectional view through the socket taken at right angles to 'the prongs, and Fig. 5 is a transverse sectional view through the device illustrated in Fig. 1. l

lReferring now to the drawing in detail, the numeral 1 designates the article to which the device is to be applied, and the inner face or walll of the said article may be concealed by a surrounding structure, so that access thereto is not readily obtainable, and whereby a nut could not successfully be sustained against the said inner face to receive a bolt passing through an opening therein.

Also the nature of the article is such that a screw could not with eiiiciency supplant the employment of a. nut and bolt, as for 1nstance, the article may be of metal, or thescrew may be subjected to a severe strain which it `could not 'for any length of time withstand.

l designates a -member 'or plate which is `provided with any number of round openings, 'only Ione being shown inthe drawing and which is designated by the numeral y2, the said opening being of a size cor-responding with the cross sectional diameter of a socket member 3.' This socket has a closed end which is tapered, as at 4, and the same has its bore threaded, as at 5, from ltsopposite or outer open end. The socket adJ'a'cent its pointed or cone-shaped end 4 is previded, at diametrically opposite points, with longitudinally 'extending slots 6, and arranged within each of these slots is a 'finger 7 which i-s pivotally secured therein, as at' 8. The ends of the slot 6 adjacent the open-end of the socket are beveled or inclined toward the tapered end of the said socket and the fingers 7 have their ends, which engage with the said walls,.inclined or beveled toward each other, sol that the sharpened ends of the fingers will lie against the beveled or inclined end walls of the slots to slightly 'project the pointed ends of the said fingers beyond the' opposite sides of the slots. The fingers are of a. width sulficient to contact witheach other when arranged within the socket which also provides for the pointed ends being projected a slight distance beyond the sides of the pocket. The socket is inserted within the opening 2, its cone-shaped end 4 being first passed to within the opening, and its outer outer face of the member l. When the device is employed as a drawer pull, a flanged 'escutcheon plate 9 provided with a bolt opening is arranged upon the outer face of the member 1, lthe opening in the's'aid member 9 registering with'the member 2. The knob or handle 10 may be provided witha screw member 11, or the said portion may be 'employed for securing the knob or handle, and this screw passes through the opening in the escutcheon plate and engages with the threads" in the bore of the socket. It should be stated that the projecting sharpened portions of the fingers 7 will contact with the opposite walls of the bore or openlng and prevent the rotation of the socket. l/Vhen the screw is rotated to draw the socket 'toward the escutcheon 9 and knob 10 thefingers 7 biting in the opposite walls provlded by the opening will be firmly embedded therein and so the knob and escutcheon will be effectively sustained upon the member l.

in Fig. 3 I have illustrated the bolt or screw 1l having a shank of a length suiiicient to contact with the oppositely rounded inner ends of the fingers 7, which Contact will force the said fingers outwardly through 'the slot 6 of the socket to force the same into engagement with the Walls of the opening 2. Should the socket pass sufficiently through the article to permit of its fingers spreading outwardly against the inner face of the said article a flanged member, similar to the escutcheon 9, serving as an abutment for the head of the screw or bolt, will force nection with the accompanying drawings,

the simplicity of the device, as well as the advantages thereof will, it is thought, bel

perfectly apparent to those skilled in the art to which such invention appertains without further detailed description.

Having thus described the invention, what l claim is: v

lin combination with an article having an opening, an interiorly threaded socket insei-ted within the opening, said socket having opposite elongated slots, the outer end walls of which being inclined, fingers piv` oted within the socket and having sharpened ends, said fingers contacting with each other and with the beveled end walls of the slots to project the sharpened ends of the fingers beyond the opposite sides of the socket, a flanged escutcheon, a screw working through the escutcheon engaging with the threaded lbore of the socket to force the socket toward the escutcheon and the sharp-- ened projecting ends of the lingers in biting engagement with the opposite walls provided by the opening in the article.

in testimony whereof l affix my signature in presence of two witnesses.
